fasterner question

could someone please tell me the size bolts used to mount motor mounts for sbc plus the size to bolt trans to engine..size and lenght please. tia

 

you need 6 each 3/8-16 NC bolts 3/4" long to bolt the motor mounts to the block..3 on each side

to bolt the tranny to the back of the block you need 6 each 3/8-16 NC bolts....the length appears to vary a bit depending on the bellhousing or tranny , but usually 1-1/4" or 1-1/2" will do
